what happened to him
These events take place soon after Aang and Katara share their kiss not years after. Benji was freaking out while his tatoos and eyes were glowing. "Whats happening ?!" He asked with a panicky voice. "Whoa it looks like me when I go into the avatar state." said Aang. Katara said " Should we take him back to the hospital?" "No I just have to cool off a bit." Benji tried to bend some air to his face only to find a fireball hurling towards him and barely blocked it in time. After he calmed down he fell out of his state and collapsed into a bush. His tatoos and eyes stoped glowing and they carried him to their house.
Aang thought that if he and Benji went into the spirit world together that they might find the answer to their problem. They went the next morning. They talked to some spirits. Benji found out that he is still an airbender but that he can change to a fire bending state.
When they got back he vowed to master his fire bending state. end of part 1
